+
+ The analyzer can generate a hash to identify reports. To debug what information
+ is used to calculate this hash it is possible to dump the hashed string as a
+ warning of an arbitrary expression using the function above.
+
+ Example usage::
+
+ void foo() {
+ int x = 1;
+ clang_analyzer_hashDump(x); // expected-warning{{hashed string for x}}
+ }
